The easiest way to turn off a calculator
I am going to share with you the easiest way to switch off a calculator. And you literally don’t have to do anything if you want to use this method. Just let the calculator switch itself off automatically. All these calculators without an “OFF” button would turn off automatically after remaining idle for a set amount of time. It is programmed to turn off automatically by the manufacturer of the calculator. So, just don’t bother and leave the calculator idle to turn itself off.
The forced methods
Now, some might feel uneasy to leave the calculator idle to turn itself off. They want to switch off the calculator on their own. How is it possible without an “OFF” button? I will share some methods which you might find helpful.
How to turn off a calculator by force?
Press the buttons in the following order :
÷ (Press Divide Button)
X (Press Multiply Button)
% (Press Percentage Button
CHECK (Press Check Button)
CORRECT ( Press Correct Button)

Another forced method
Most of the calculators nowadays have solar charging facility. Solar calculators get automatically charged by the solar power.

Once the calculator stops receiving solar power, it will switch off automatically.
Turning off Casio Calculator
There are many users who have asked specifically to turn off Casio calculators. As I explained earlier, most calculators come with auto turn off features. You just have to leave it idle and your calculator will turn off automatically.
Still, if you want to shut it off by force, the few methods suggested below might work:
Press & hold the 1,3,7,9 and AC button simutaneously. Release the AC button first and then, release the other buttons.
First, press the AC button. Then, press & hold the DISP and CORRECT button. Release the DISP button first and then, release the CORRECT button.
In both the above methods, you will see that the display of the calculator becomes blank. But, the power is still on. It will take few minutes to turn off. Before turning off, you will see CASIO text displayed.
The best method to switch off is to let it turn off on its own. If you want to turn off by force, I have explained the various methods you can use. You can try any of these method and let me know your feedback with the Calculator Model Number.
